The forward and back of the screw thread of valve rod, thus promote or decline the valve plate being connected with valve rod, reach the effect opened and closed.Relative to
By lever brake valve, Outside screw stem rising through handwheel type gate valve size is bigger, and opening and closing is more laborsaving, and valve rod does not contacts with fluid, and sealing surface is difficult to be rushed by fluid media (medium)
Erosion, can preferably adapt to the operation of damming between high pressure pipe joint.
But the valve rod epimere of Outside screw stem rising through handwheel type gate valve is outdoor structure, along with the rotation of handwheel, valve rod epimere exposes the length of valve body
Also can respective change, for strengthening the preservative efficacy of naked section, the most all uses stainless steel material processing valve rod, and coating butter,
But nonetheless, due to oil gas field work on the spot bad environments, sandstone dust etc. easily drops to adhere on valve rod and by butter,
Causing rotation difficulty, in some instances it may even be possible to scratch sealing surface, the when of simultaneously because install, valve rod is screwed into closed mode under being mostly,
If installation site is unreasonable, then may result in cannot on be screwed into the position of standard-sized sheet, make troubles to use.
Utility model content
For the problems referred to above, this utility model provides a kind of simple in construction, the connection epimere that is provided with easy, good stability to protect
The Outside screw stem rising through handwheel type gate valve of sheath, it can reduce the foreign body of gate valve upper end and enter, assist to determine when installing height, simultaneously in transportation
Also can take off protection set and save space.
The technical solution of the utility model is:
A kind of Outside screw stem rising through handwheel type gate valve being provided with epimere protection set, including valve body, flashboard, valve gap, valve rod, handwheel, protection set；Described
Valve body is hollow structure, and flashboard is installed in the middle part of valve body, and upper end connects valve rod, and valve rod hypomere is light bar segment, through being provided with sealing
After the valve gap of device, epimere is trapezoidal thread, and handwheel is placed on trapezoidal thread and is fixed on above valve gap by bearing；Described hands
In the middle part of wheel, top is provided with a circle thread groove；Described protection set is hollow cylinder, and cylinder inside height and valve rod move on to top
The most identical, upper side is provided with an oil filler, and lower end outside is provided with thread segment, and thread segment can be with precession thread groove.
Preferably, described protection set internal diameter 2mm bigger than trapezoidal thread internal diameter.
Preferably, described protection set is transparent material, is decorated with scale above.
Preferably, the oil filler of described protection set side can connect grease gun.
Preferably, described oil filler, with plug, blocks oil filler in working order, it is to avoid foreign body enters.
Preferably, described protection set lower end is provided with rubber blanket, strengthens sealing effectiveness, prevents the internal butter of protection set from revealing.
The beneficial effects of the utility model are:
1, by arranging protection set, the foreign body reducing Outside screw stem rising through handwheel type gate valve valve rod naked section enters, it is ensured that valve rod rotates smooth and easy；
2, protection puts and is provided with oil filler, it is simple to add butter；
3, transparent protection puts and is provided with scale, it is simple to observes and puies forward degree, to determine flashboard aperture on valve rod；
4, the when of gate valve being installed again to manifold, because being provided with protection set, valve rod extreme higher position can be got information about, just
In reasonable arrangement space.
